Akira AJISAKA commented on HDFS-5978:
-------------------------------------

bq. I appreciate if you can separate it into a new jira.
I'll separate it.
bq. I don't quite follow why you need an extra pipeline stage to dump the 
string into the channel buffer.
The pipeline stage is to encode UTF-8 String to the channel buffer. It is 
required to dump UTF-8 String directly to the channel buffer.
Or do you mean ChannelBuffer should be used instead of String to create a 
response content?

> Suggested in HDFS-5975.
> Add an option to exposes the read-only version of WebHDFS API for 
> OfflineImageViewer. You can imagine it looks very similar to jhat.
> That way we can allow the operator to use the existing command-line tool, or 
> even the web UI to debug the fsimage. It also allows the operator to 
> interactively browsing the file system, figuring out what goes wrong.
